I don't know the stuff you speak of, but when I worked in a restaurant the kitchens (totally brand spanking new in 2001) had the walls covered with some kind of plastic. This appeared to be moulded to shape and welded at joints as it was seemless, for hygiene reasons. Probably used in operating theatres too.
It reminded me of those resin floors that you get in minimalist-style buildings.
Perhaps if you check with a commercial kitchen suppliers you can find out if they sell it and see how it compares against the material you intend to use (with regards to type of plastic and how to fit it).
